Sansui manufactured Very good quality consumer Hi Fi in the 1970s. Sansui claim a number of "firsts" , rightly or wrongly , including First Audio Transformer; First High Powered Tube-transistor Amplifier; First in the World with matrix "surround sound" in 1970; Stereo AM in 1976 and Digital Sound Processing in 1983, to mention but a few.Now sought after by those seeking to buy the goodies they couldn't afford 3 decades ago. Do not confuse this earlier Sansui equipment with the junk being retailed nowadays in Australia (and perhaps other countries) under the same name.
1971 Advert for the Sansui 5000 X AM/FM Multiplex Receiver. One that you would be still proud to own!
